Would you please explain it to me? Thank you very much.

Yan: hmm ... what should I say? "This is the key to my bedroom. . . "

The color separation keys are:

Black represents darkness, terror and evil. . . Therefore, it is the key to hell.

White represents purity, nobility and kindness. . . So it is the key to heaven.

Pink represents ambiguity and temptation. . . The role of sexual concealment. . .

Well, this is a vulgar adult joke, there is no need to delve into it.
